BS EN provides information on: the underlying concepts of risk and the relationship of risk to safety integrity (see Clause A.4);. BS EN , Functional safety – Safety instrumented systems for the process industry sector, is the benchmark standard for the management. IEC is available as IEC RLV which contains the International Standard and its Redline version, showing all.

However, it is often their sb that can lead to 611511 and therefore they should be designed to good practice requirements. Note, however, that is not harmonized under any directive of the European Commission. List of International Electrotechnical Commission standards.

IEC provides good engineering practices for the application of safety instrumented systems in the process sector. IEC standard is a technical standard which sets out practices in the engineering of systems that ensure the safety of an industrial process through the use of instrumentation. Click to learn more. Functional safety Functional safety is the part of the overall safety of plant and equipment that depends on the correct functioning of safety-related systems and other risk reduction measures such as 615111 instrumented systems SISalarm systems and basic process control systems BPCS.

SIS SIS are instrumented systems that provide a significant level of risk reduction against accident hazards. BPCS are normally designed for flexible and 615111 operation and to maximise production rather than to prevent accidents. IEC covers the design and management requirements for SISs throughout the entire safety life cycle.
